Custom Server Controls :: Find Controls Present Inside Template Field?

Jan 11, 2011

I am writing a custom control and implementing ITemplate in it. The code that I am using can be reviewed at the following link: http://msdn.microsoft.com/en-us/library/ms178657.aspx

Under the Template field, I would only like to allow controls of specific type only, say LinkButton and TextBox. If any control(s) present inside Template is anything except LinkButton or TextBox, an error should be thrown. I am wondering how can I check it programmatically inside custom control. The problem is that there is no collection available that lists all the controls that of Template (or may be I am not aware of it.)

Custom Server Controls :: How To Make Controls Inside A Template Visible To Code-behind

Nov 27, 2010

I have created a custom control that implements Templates (based on Panel controls) ... I can do a FindControl to locate imbedded controls. This allows me to get and set values in the imbedded controls, but I want to be able to reference the imbedded controls like they are properties of the associated panel. Here is a sample of how my custom control now works:

<cc:CustomControl ID="myCustomControl" runat="server">
<PanelTemplate>
<asp:TextBox ID="myTextBox" runat="server"></asp:TextBox>
</PanelTemplate>
</cc:CustomControl>

I can do the following (where my custom control has given the panel hosting the template the name "myPanel"):
Dim txt As TextBox = myCustomControl.myPanel.FindControl("myTextBox")
txt.Text = "Some text to put in TextBox"

What I want to do is:

myCustomControl.myPanel.myTextBox.Text = "Some text to put in TextBox"

Custom Server Controls :: See If Custom Control Is Already Present

Mar 9, 2010

I'm trying to create a custom control that will add both javascript and css. This is a pretty generic control that I can reuse on a page. How can I check to see if the script /style is already there so I don't have to render it over and over? If I can check to see if that control is already rendered, I could skip the script part.

Forms Data Controls :: Fetch Gridview Edit Template Field In Custom Validator?

Jan 29, 2010

I have an edit template on gridview which opens a text box and button with a custom validator .

On button press I have to validate the text in edit item template with a text field in gridview row template.

I am having a hard time fetching the data of the edit template textbox. Even though both custom validator and textbox are in same edit item template but intellisense is not picking it up.

Also the custom validator server_validate event is using "object source" instead of "object sender"

How do I fetch the edit item template text for comparison

I am doing this as

protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
GridViewRow gvrow = (GridViewRow)(source as Control).Parent.Parent;
int index = gvrow.RowIndex+1;
// TextBox txttmp=(TextBox)
Label lbl = (Label)gvComp.Rows[index].FindControl("lblSecShare");
decimal CSh = Convert.ToDecimal(lbl.Text);
}

Custom Server Controls :: How To Get The Value Of Readonly Properties Of Server Controls Inside A Custom Server Control

Apr 4, 2010

I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.

Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?

I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

Forms Data Controls :: Raise Click Event Of A Linkbutton Inside A Template Field That Was Created Programmatically

Jan 28, 2011

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

Custom Server Controls :: Server Controls Inside Asp:wizard, Doesnt Render Html When Step Is Not First?

Sep 30, 2010

I have a server control which consists of a gridview with custom navigation&information capabilities and with javascript functions to highlight the selected grid items or highlight when mouse over event occurs.. (full tested outside asp:wizard)I'm trying to use that server control inside a template wizard step, when I drop such server control in the first step of the wizard everything goes ok.

When I insert even a blank step previous to the step which contains the server control, the javasript code of the server control is not rendered at all, the page doesn't fail during load but until I go with mouse over an item of the grid for instance.When I check the rendered HTML I can see no HTML, nor javascript events of this server control where rendered, neither the implementation nor calls to javascript, but even rarer what is there visible in the grid for ie, even the other components of the server control, are not in the "view source code" content. I seems it was sent to the client, even showed, but truncated in some phase..

Custom Server Controls :: Adding Template In Design Time?

Mar 13, 2010

i create a custom control which can hold some templates, such as Header, Body Footer, etc.

[Code]....

i tried to use smarttags to allow the user to edit each of the templates, which worked pretty well. what i could not get working was to add a template if it has not been in the control. eg. add a header-template to the control above. i tried using the RootDesigner.AddControlToDocument() function of my controldesigner. but this function gives me an error, telling me the control i'm going to add the template (i used a new HtmlGenericControl("HeaderTemplate") as new Control) to is not valid. (i can't give the exact error message, cause i use a german version of visual studio 2008) i've been searching the web for nearly half a day now, but i did'nt find a working solution for my problem.

Sep 9, 2010

I have a gridview which the columns are created programmatically.

When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
